Subject: [PATCH v1 0/2] Get DMA information from real IOMMU
Date: Wed, 9 Jan 2019 13:41:52 +0100 [thread overview]
Message-ID: <1547037714-21592-1-git-send-email-pmorel@linux.ibm.com> (raw)
The zPCI driver needs to get specific information from the host
IOMMU.
In this patch, the IOMMU DMA start and end usable addresses are
retrieved using the VFIO_IOMMU_GET_INFO iotcl by introducing
capabilities to the vfio_iommu_type1_info structure.
